1 + 1

Here’s a Philip Glass composition you can play yourself, as printed in Score: An Anthology of New Music (out of print I assume but probably findable in a university’s library):



Any table top is amplified by means of a contact mike, amplifier and speaker.

The player perfoms 1 + 1 by tapping the table top with his fingers or knuckles.

The following two rhythmic units are the building blocks of 1 + 1:

a) sixteenth note – sixteenth note – eighth note

b) eighth note

1+1 is realized by combining the above two units in continuous, regular arithmetic progressions.

The tempo is fast. The length is determined by the player.
